14. The Lord also spoke unto Moses in the wilderness of Sinai, saying,
15. Number the sons of Levi by the houses of their fathers, by their families; thou shalt number every male from a month old and upward.
16. And Moses numbered them according to the word of the Lord, as he was commanded.
17. And these were the sons of Levi by their names: Gershon and Kohath and Merari.
